Engine Keeps Dying In Wet Weather Only

Hey all it's been a while

I'm having trouble with my 08 Ninja 250. Everytime it rains, my motorcycle will not want to start. It turns over, sometimes I can hear it fire a couple times, but the engine ends up dying.

Water I think is somehow getting into my tank/fuel. Everytime this happens I have to drain the tank and then fill with fresh gas, then it'll fire up fine after a couple cranks.

I've had my gas cap gasket changed with oem ones (locks had to be replaced on bike due to someone damaging my ignition so I ended up changing all locks and the gasket) and this problem still exists.

I'm wondering are there any other sources I should look for in terms of water getting into the tank. I don't see or smell any obvious places that water could get in.

I'm about to book a day at MotoGuild on treasure island in San Francisco to try and sort though this problem, so I'm trying to get some other ideas so I can pair down the cause of this
